September 30, 2008Q: When is it too late to wear a white cotton suit? What if it is still warm at the end of September?--Ben

We've previously set rules on white jeans (which were then copied by GQ's Style Guy in the July 2008 issue). The window for a white cotton suit is quite a bit smaller. Unless you're south of 26 degrees North latitude (about Ft. Lauderdale, FL), a strict Memorial Day-Labor Day rule is enforced.
